About the Airtac MIJ Adjustable Cylinder MIJ16X40-30
Dial in your forward end position on the fly with the AirTAC MIJ16X40-30, a round-body stainless steel mini cylinder built for double-acting operation. An external stop screw lets you shorten the extend stroke by up to 30 mm directly on the machine, meaning one part number can cover several intermediate stops between 10 mm and 40 mm without swapping hardware. Retract remains at the full 40 mm. The riveted stainless barrel and piston rod supply mild corrosion resistance for washdown environments.
It features an M5×0.8 port, an M6x1.0 male rod thread, and conforms to the ISO 6432 mounting interface for easy bracket interchangeability. Fixed TPU bumper pads decelerate the stroke ends. Note this specific SKU lacks a magnet, so it cannot host CMSG, DMSG, or EMSG sensors without upgrading to the -S variant.

Specifications follow the official AirTAC MI/MIC (ISO 6432) datasheet. Barrel & rod: stainless steel (round-body, riveted construction). Thread options: PT (blank) / G.
Theoretical Output Force (Ø16mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 86 N |
| 0.7 MPa | 121 N |
| Max (@1.0 MPa) | 18 kgf |
MIJ / MICJ are double-rod: the rear rod that carries the stroke adjuster exits the rear cover, so both piston faces lose rod area. The rod-side (annular) area is used for both directions (conservative).

Where the Airtac MIJ Adjustable Cylinder MIJ16X40-30 Is Used
Staged Part Ejection
Use the 30 mm extend adjustment to push a 5 kg workpiece to a variable intermediate stop, accommodating different fixture depths without changing the cylinder.
Tooling Changeover
Leverage the stainless build and adjustable forward end position to quickly reset a 40 mm stroke to a 15 mm stop when swapping machining fixtures on the same line.
Is the Airtac MIJ Adjustable Cylinder MIJ16X40-30 the Right Cylinder?
The Ø16 hits a solid middle ground at 100.5 N. The 30 mm adjust window is highly useful for taking up mechanical tolerances or staggering part ejection during changeovers. Keep in mind the stop screw only sets the forward end position; it is not a mid-stroke lock. Because a standard cylinder drifts on air loss, add an external rod lock or pilot check valve if you need to hold a vertical load safely.
Mounting options include LB foot, FA flange, and TC trunnion brackets, along with CA, U, R, or CM back covers. The SDB pivot block is not available on this adjustable-stroke series. Operating speed ranges from 30 to 800 mm/s at pressures between 0.15 and 1.0 MPa.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G)
- ✓ Magnet (-S) for sensors?
- ✓ Back cover (CA/U/R/CM) & mount (LB/FA/SDB/TC)
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Do not dismantle the riveted front/back covers.
- check Use correct back cover (CA/U/R/CM) & mount (LB/FA/SDB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac MIJ Adjustable Cylinder MIJ16X40-30 FAQ
This double-acting cylinder uses an M5×0.8 port and an M6x1.0 male rod thread. The theoretical maximum force is 20.5 kgf at 1.0 MPa.
An external stop screw shortens the extend stroke by up to 30 mm on-site, allowing you to set the forward end position anywhere from 10 mm to 40 mm. The retract stroke remains fixed at the full 40 mm. This SKU does not have a magnet for sensors; you would need the -S variant for CMSG, DMSG, or EMSG switches.
